Specs are for the stock bike as sold; check your own bike before you buy. This page covers the Rail+ Gen 5 with 160 mm of travel front and rear. It uses the updated, quieter Bosch Performance Line CX on the smart system; see Bosch motors explained. The battery locks with a 6 mm hex key, and a keyed ABUS version is available. Earlier Rail models used different batteries and displays.
Electrical parts on this list must match this exact model and are fitted at the external plugs or by a pro. Never open the battery, motor, display or remote. Battery and motor service on the Bosch system is dealer work: a Bosch dealer reads faults with its diagnostic tool.
Parts list
- Tire: mixed wheel (MX) setup on every size except Small, which runs 27.5 inch front and rear. Keep the stock wheel sizes.
- Tubeless sealant: every Rail+ ships set up tubeless.
- E-bike charger: a full charge of the 800 Wh battery from empty takes about 7 hours.
